Evaluation of the concentration of allergens from mites in fur of household dogs (Canis lupus familiaris) in Curitiba - PR - Brazil

Background Allergens from house dust mites are perennial and also have enzymatic nature. They are commonly found in bedding, mattresses, pillows, bedroom floor and living room. In addition, they are often associated with sensitization and intensification in the symptoms of allergic rhinitis and asthma for susceptible individuals. Household dogs are continuously in contact with the ecological niches of house dust mites, and it has been observed that the microclimate between their skin and coat may favor its proliferation. Therefore, the present study aims to evaluate the concentrations of Der p 1, Der f 1 and Blo t 5, in the fur of household dogs, in order to check if they can serve as a reservoir of such allergens in the environment.
